During the recording sessions for their (Liquid Tension Experiment) second album, John Petrucci had to leave due to his wife, Rena, going into labor. During that period, the remaining members, who still had studio time booked, continued to write music in improvisation. On October 23, 2007, a compilation of jams from those sessions was released under the name of Liquid Trio Experiment. The album is called Spontaneous Combustion. A few songs from Liquid Tension Experiment 2 were spawned from these jam sessions, including "914", "Chewbacca", and "Liquid Dreams".
